1 claim. (ci. zoo-,44)`

This invention appertains to new and useful improvements in protecting switches for motor vehicles and principally automobiles and the principal object is to provide a novel switch means for cutting olf the battery from the various electrical features of the vehicle to the end that a short circuit cannot occur and at the same time providing a safeguard against the theft .of the vehicle. p

During the course of the following specification other important objects and advantages of the invention will become apparent to the reader.

In the drawing Figure 1 represents a longitudinal vertical sectional view through the protector.

Figure 2 represents a horizontal sectional view through the switch. l

Figure 3 represents a diagrammatic view of the elements of the switch in association with the current supply.

Referring to the drawing wherein like numerals designate like forms, it can be seen that numeral 5 represents a casing provided with a removable top 6. In the casing 5 are the grooved retainers 'I--l for supporting the dielectric panel 8. This panel 8 is provided with a pair of contacts 9 8 having on one side thereof, threaded shanks 9B which extend through the panel and are equipped with nuts Il, thus forming binding posts to which the battery lead i2 can be resents the fixed pin disposed between 'the side walls of, the casing 5 and rockable on this is the dielectric link member I8 arranged in parallel relation pv/,with the shank I8 secin'ed at one end between the upper'` ends of the links I8. The shank i9 has the leaf spring contactar 2| secured thereto andhas an (extension slidable thromh the partition 8. f i

The pin 20 is provided at its intermediate point with an Aopening for receiving the pivot pin 22 extends through the slot 23 at the lower ends of the dielectric links I8 and as can be seen in Figure 1, the elongated control rod 24 provided with 5 a knob 25 at its outer end extends into the casing 5 and is bifurcated at its inner `end and perforated to straddie the intermediate portion of the pin 20 and receive the pivot pin 22. Pin 28 has a stop ange 26 thereon between which and the panel 8 a coiled extensible spring 21 is located.

As can be seen in Figure 1, it will be understood that when the driver is about to en the 5 automobile, he unlocks the lock i4 by way of a suitable key 28 winch retracts the bolt i5 and frees the pin 20 so that the spring 21 forces the piu 2li toward the left in Figure 1.

The leaf spring contactor 2| now bridges the 10 contact 8 5 so that the current can travel from the battery 28 by way of the lead i2 of the switch and the jumper I3 to the electrical features of the vehicle.

When the driver is about to leave his car and 15 wants to guard the same, he forces inwardly on the rod 2l which moves the bolt 2l toward the right in Figure l against the action of the spring 21 and results in the bolt i6 engaging into a notch in therod 2l. This action rocks thelinks I8 and 20 causes removal of the contactor 2l from the corntact 8-8. Thus the lead of abattery is broken so that no short circuit can occur in the appliances or electrical features of the vehicle.

Having described the invention, what is claimed 25 as new is:

A switch of the character described comprisingacasingprovidedwltharemovableclosm-e at one side thereof, a pair of guides in the casing-,' one at the top and one at the bottom thereof, a 30 dielectric partition in the casing having its upper and lower edges .encased into the slide and being removable with respect thereto, a pair of emtacts on the dielectric partition at one side 35 thereof.abindingpost attheoppositestdeofthe partitbn and extending through a connection with the contacts, a rocker ofY dielectric material mounted inthe casing and provided with ahand rod extending throughone end of the casing@ whereby the rocker can be oscillated, said hand rod being pivotally connected to the lower end of therocker, aguiderodextendingfrom l, same end ottherocker andthroughanope/ninginthe partltionandbeingdetaohablyconectedwith respect to the rocker, a spring on'tiie rod interposed between the rocker `and the partition, 'a contacter onthe upper end of the rocher for engagement with the contacts, a detectable connection between thecontactor and the rocker, and 5 a guide rod extendingfrom the contacter and through an opening in the partition.
